Title: Improvements in milling cutters with detachable tools, and methods of mounting the cutting tools in the same
IPC: B23C5/24
Filed: 1947-08-26
Abstract: 626,812. Milling-cutters. SANDVIKENS JERNVERKS AKTIEBOLAG. Aug. 26, 1947, No. 23580. Convention date, Oct. 4, 1946. [Class 83 (iii)] A detachable blade milling-cutter with means for clamping each blade against the side wall of its groove in the body portion, has the side of the tool facing the bottom of the groove resting thereon at a point near the front end while the rear part of the tool is spaced away from the bottom of the groove. In one form of tool for end-working, Fig. 2, the grooves 4 in the body are tapered towards the rear of the tool giving a bearing point at 8 for the tool 2, its rear end 7 being spaced from the groove bottom. Clamping screws secure the cutter against a side face of the groove. This enables the cutters to be set by engaging the cutting edges with a step 10 in a work-piece or template and moving it until the bearing point 8 is contacted. The cutters may be set at differing projections by the use of a stepped template. In another form of tool, Fig. 10, the cutters 18 are located in inclined grooves in the face of the cutter body and are located at 20. Wedges 22, Fig. 11, may be used to secure the cutters, these being moved against the side face of the tools by further wedges 21 and screws 23.

Abstract: 923,892. Electrical resistance measuring. HEWLETT-PACKARD CO. July 10, 1959 [Aug. 18, 1958], No. 23858/59. Class 37. In a direct-reading multi-scale ohmmeter wherein the resistance of a component 87, connected by leads having a finite resistance 71, 77 to a calibrating resistance 39 energized from a voltage-regulated source 18, is measured by a voltmeter 81, resistor 41 in parallel with the series combination of resistors 29, 31, 33, 35, 37 provides an additional current through the calibrating resistance whereby the lead resistance is compensated. Resistor 23 is adjusted for full scale deflection of the meter when the test terminals 73, 79 are open circuit to eater for variations in the characteristics of tubes 21. Compensation for the shunting effect of the meter on higher ranges is achieved by the selection of values of the additional calibrating resistors and series resistors, the mathematical basis for such selection being described. Reference is made to the use of a valve voltmeter in conjunction with the apparatus for the measurement of insulation resistance.

[Also in Division B1] Confectionery compositions are prepared by dissolving sugar in water in heated-pan 3, allowing the solution to flow over frustoconical heating elements 16 and 17 and then evaporating water from the solution by causing it to flow over frusto-conical heating elements 25, 26, 27, 28, the pan 3 and all the heating elements being accommodated in the same housing. Pan 3 is heated by a steam-jacket and by coils 5, 6 and 7, and is provided with stirring blades.

Elements 25, 26, 27, 28 are connected with an independent supply of steam. Sugar is introduced into the housing by worm 13 and preheated water is supplied through pipe 11. The sugar solution flows over the rim of pan 3 and pours down on to heating- element 16. While flowing inwards over the hot surface of element 16, the last particles of sugar are dissolved. The solution then flows outwards over element 17, flows off it at a temperature of 90‹-95‹ C., and is collected in pool 18 on heating-element 19.

After flowing over all the evaporating elements, the finished composition is collected in pan 30. The vapours evolved in the evaporating chamber are drawn off through pipe 29, which is connected to a suction pipeline.
